    103103 * '''Extracting data''' as Matlab arrays. Information stored in the GUI uvmat  (as ''!UserData'' in the figure) can be extracted in the Matlab work space by the menu bar command  '''[Export/field in workspace]''' (or by pressing the right mouse button on the GUI). Type '>>Data_uvmat.Field' to get the current input field as a Matlab structure. An image or scalar matrix is for instance obtained as Data_uvmat.Field.A.

    337337In summary, the ''field structure'' is specified by the following elements:
    338338
    339  * (optional) '''!ListGlobalAttribute:''' list (cell array of character strings) of the names of global attributes  Att_1, Att_2...
    340  * (mandatory) '''!ListVarName:''' list of the variable names Var_1, Var_2....(cell array of character strings).
    341  * (mandatory) '''!VarDimName:''' list of the dimensions associated with each variable: this is a cell array whose number of element is equal to that of '''ListVarName'''. Each element is the dimension name for a unidimensional variable, or a cell array specifying the list of dimension names for a multidimensional variable.
    342  * (optional) '''!VarAttribute:''' cell array of structures of the form !VarAttribute{ivar}.key=value, defining an attribute tag name and value for the variable #ivar (variable number in the list !ListVarName]).
     339 * (optional) '''!!ListGlobalAttribute:''' list (cell array of character strings) of the names of global attributes  Att_1, Att_2...
     340 * (mandatory) '''!!ListVarName:''' list of the variable names Var_1, Var_2....(cell array of character strings).
     341 * (mandatory) '''!!VarDimName:''' list of the dimensions associated with each variable: this is a cell array whose number of element is equal to that of '''ListVarName'''. Each element is the dimension name for a unidimensional variable, or a cell array specifying the list of dimension names for a multidimensional variable.
     342 * (optional) '''!!VarAttribute:''' cell array of structures of the form !VarAttribute{ivar}.key=value, defining an attribute tag name and value for the variable #ivar (variable number in the list !ListVarName]).
    343343 * .Att_1, Att_2... : values of the listed global attributes.
    344344 * .Var_1, .Var_2...: variables arrays whose names are listed in !ListVarName.
     
    346346In some cases, it is useful to define the field object independently from its data content. Then the variables .Var1... are replaced by the lists of dimension names and values.
    347347
    348  * '''!ListDimName:''' list of dimension names (cell array of character strings)
    349  * '''!DimValue:''' array of dimension values corresponding to !LisDimName.
     348 * '''!!ListDimName:''' list of dimension names (cell array of character strings)
     349 * '''!!DimValue:''' array of dimension values corresponding to !LisDimName.

    351351The following temporary information is added to manage projection and field substraction oerations, which must be done in general after projection:
     
    564564-''' Plotting calibration points: ''' press the menu bar command button '''[Plot] ''' to visualise the list of calibration points. The physical or image coordinates will be used in the list '''[!ListCoord]''', depending on the option 'phys' or 'px' in the menu '''[transform_fct]''' of ''' uvmat.fig''' .
    565565
    566 -''' Appending  calibration points with the mouse: ''' Calibration points can be manually picked out by the mouse (left button click) after a calibration image has been opened by '''uvmat.fig''' (with the option 'blank' in the popup menu '''[transform_fct]'''), and the option '''[mouse_active]''' (at the very bottom) has been selected. Zoom can be used to improve the precision, but must be desactivated for mouse selection (then move across the image by the key board directional arrows). The coordinates in pixel of the selected points get listed in the box '''[!ListCoord]''' of '''geometry_calib.fig'''. A calibration point can be later adjusted by selecting it with the mouse and moving it while pressing the left mouse button. Points can be accumulated from several images (use the key board short cuts 'p' and 'm' to move in the image series without monopolising the mouse).''''
